Title: plugins.php and update-core.php: Page not found Last modified: August 30, 2016 --- # plugins.php and update-core.php: Page not found * [kfullerton911](https://wordpress.org/support/users/kfullerton911/) * (@kfullerton911) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/) * I’m trying to add a plugin, but when I click on the admin page, I get the blank page of “Oops! That page can’t be found.”. I renamed my plugins folder to deactivate it in my file manager, but I still get the same “Oops! That page can’t be found.” page. * I am currently using the current version of wordpress 4.2.4. When I deactivate my plugins folder, I still get the notifiaction of “1” to update on my plugins bar and updates bar.

I did find a suggestion on the forums from a long ago problem and it seems to have fixed it for me. You need to access the .htaccess file in your root WordPress directory. Then just add the following line: * `AddHandler application/x-httpd-php5 .php` * After that it should work. This line makes sure that PHP 5 is used for the site, seems that something was reciently changed to be sensitive to PHP5. * Thread Starter [kfullerton911](https://wordpress.org/support/users/kfullerton911/) * (@kfullerton911) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449859) * Thanks so much gilmansean! Was really simple and fixed the problem. Would send you a cookie if I could, but since I can’t, I’ll eat if for you. nom nom nom * [allmedianeeds](https://wordpress.org/support/users/allmedianeeds/) * (@allmedianeeds) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449860) * I tried to add the line but it didn’t work on my end. It keeps giving me this: * > Internal Server Error > The server encountered an internal error or misconfiguration and was unable > to complete your request. > Please contact the server administrator, [webmaster@nugeeks.com](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/webmaster@nugeeks.com?output_format=md) > and inform them of the time the error occurred, and anything you might have > done that may have caused the error. > More information about this error may be available in the server error log. > Additionally, a 404 Not Found error was encountered while trying to use an > ErrorDocument to handle the request. * Any idea of what went wrong, doing it on all my sites. * [gilmansean](https://wordpress.org/support/users/gilmansean/) * (@gilmansean) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449863) * Sounds like there might be something wrong in your .htaccess file. Can you post the contents of your .htaccess? Make sure to blank out any sensitive info. Can you also check the file permissions on it? * [kithren](https://wordpress.org/support/users/kithren/) * (@kithren) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449880) * I had the same error, however my fix was slightly different. In my .htaccess file, I had the following line already in there: * AddHandler application/x-httpd-php52 .php .php5 .php4 .php3 * Looks like things were set up for PHP 5.2, but this causes the 404 error for me. By getting rid of the pesky “2”, suddenly things worked: * AddHandler application/x-httpd-php5 .php .php5 .php4 .php3 * Not sure if this will help you, but gilmansean certainly pointed me in the right direction. * Quick note for those using Cpanel file manager – be sure to click the “show hidden files” option in file manager or you won’t see the .htaccess file. Once I checked the option, I was able to get into the file and use the file manager “edit” option to fix things. Before I paid attention and clicked the “show hidden files” option, I was a wee bit confused… * [allmedianeeds](https://wordpress.org/support/users/allmedianeeds/) * (@allmedianeeds) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449881) * [@gilmansean](https://wordpress.org/support/users/gilmansean/) you were right, the .htaccess file in the root directory needed to be modified. I went ahead and edited the line as stated by [@kithren](https://wordpress.org/support/users/kithren/) and it worked, thank you both for this helpful information since it was a lifesaver! Thank you both so much! * [gilmansean](https://wordpress.org/support/users/gilmansean/) * (@gilmansean) * [10 years, 9 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449890) * Glad it is working. Just to make sure I give credit where it is due I found the post that gave me the fix, [https://wordpress.org/support/topic/not-found-update-corephp-themesphp-and-pluginsphp?replies=3](https://wordpress.org/support/topic/not-found-update-corephp-themesphp-and-pluginsphp?replies=3). That post has some other issues and info that does not seem related to the problem I was having, but one of the fixes mentioned is what worked for me. * Just a FYI post, no more useful information. I just would hate to have someone think I stole their idea! * [ronaldosoo](https://wordpress.org/support/users/ronaldosoo/) * (@ronaldosoo) * [10 years, 5 months ago](https://wordpress.org/support/topic/pluginsphp-and-update-corephp-page-not-found/#post-6449983) * > I was having this issue, upgrading from 4.2.4 to 4.3 did not fix.
